Ice/Water dispenser not working

The front door water/ice dispenser on my side by side does not work. All functions --light, and other options are dead. Appears that there is no power to the keypad or circuit board. I took the harness connection apart on the top of the freezer door and jumped two wires and the ice cube auger started to turn. Jumped two more and the water started to come out the door so I have it narrowed down to the dispenser area of the fridge. Anyone see this issue? What fails most often? I don’t want to spend extra money throwing parts at it. Would be great if I could get used parts that work.

Thanks Guys for you help in advance.
